No. If you divide 69 by 100 you would get 0.69. If you divided 6 by 10 you would get 0.6. Therefore 69/100 and 6/10 is not equivalent.
Asuuing yo meant (h,k)=(-5,1/2)
equation is

(h,k) is center and r=radious
given that (h,k)=(-5,1/2) and r=1
h=-5
k=1/2


if you wanted us to expand
x
²+y^2+10x-y+25.25=1
Answer:
not sure about 1
for number 2 it is 5 over 4 . for y, 5 10 15 20 is a multiple of 5 so the change is 5. for x, 4 8 12 16 is a multiple of 4 so the change is 4.
Honestly I don't know that is a really hard question
